RE: st: AW: Keeping variable After restore

I don't think there is any rule against an option called -if()-. However, a programmer would have a hard time supporting -if- and -if()- together and it would generally be considered Bad Style.

That should read
factor wbq91-wbq93 if year == 2005, factors(1)
Remember that -if- is never an option and should thus
appear before the ","
